L-CutA trim notch in a film resistor that is created by the cut starting perpendicular to the resistor length and turning 90 degrees to complete the trim parallel to the resistor axis thereby creating an L-shaped cut

Laminar FlowA constant and directional flow of filtered air across a clean workbench. The flow is usually parallel to the surface of the bench.

LandsWidened conductor areas on the major substrate used as attachment points for wire bonds or the bonding of chip devices.

Laser TrimThe adjustment (upward) of a film resistor value by applying intense localized heat from a focused laser source to vaporize material.

LayoutThe scale depiction (drawing) in two dimensions of all conductors, resistors and other circuit elements to be fabricated as a film substrate.

LCCLeadless Chip Carrier.

Life DriftThe change in either absolute level or slope of a circuit element under load. Rated as a percentage change from the original value per 1000 hours of life.

Life TestTest of a component or circuit under load over the rated life of the device.
